Specification of Letters Patent.

Patented Oct. 2, 1906.

Application filed October 23, 1906. Serial No. 283,991.

To all whom, it may concern.-

Be it known that I, MARTIN LUTHER Pon- TER, a citizen of the UnitedStates, residing at Bedding, in the county of Shasta and State ofCalifornia, have invented certain new and useful Improvements inVehicle- WVheels; and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to improvements in vehicle-wheels, and moreparticularly to the hubs thereof and the means for securing the spokestherein.

The object of the invention is to provide a simple, durable, andcomparatively inexpensive wheel-hub in which the spokes will be firmlysecured and in which they may be quickly replaced when broken.

With the above and other objects in view the invention consists ofcertain novel features of construction, combination, and arrangement ofparts, as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a perspective view of the hubof a vehiclewheel constructed in accordance with my invention. Fig. 2 isa longitudinal sectional view through the same. Fig. 3 is a perspectiveview of one of the clamping-collars, and Fig. 4 is a perspective view ofthe inner end of one of the spokes.

Referring to the drawings by numeral, 1 denotes my improved vehiclewheel hub, which comprises a bearing-sleeve 2, formed with a bore to fitthe spindle S of a vehicle axle A. At the enlarged inner end 3 of thesleeve is formed an annular stop flange or collar 4, on the outer faceof which is a polygonal surface 5, which is adapted to be engaged by awrench or the like when the parts of the hub are being secured togetheror sep arated, as presently explained.

Adjacent to the reduced outer end 6 of the bearing-sleeve are formedscrew-threads 7, which are adapted to be engaged by similarscrew-threads formed in a clamping-nut 8. The latter is in the form of atube or sleeve having at one end an annular collar or flange 9, on theouter face of which is formed a polygonal surface 10, similar to thesurface 5. When wrenches or the like are engaged with the two surfaces 510 ,the nut may be quickly screwed onto or off the bearing-sleeve. The

outer end of the nut 8 has its interior recessed or reduced, as at 11,for a purpose presently explained.

The spokes 12 of the wheel are adapted to be removably clamped betweentwo clamping disks or plates 13, which are placed upon thebearing-sleeve between the collar 4 thereof and the collar 9 of the nut.Each of these disks or plates 13 is formed with a central opening 14. toreceive the bearing-sleeve and with an inwardly-extending annular flangeor rim 15, so that the disk or plate is dished or of concave form. Theinner face of the flange or rim 15 consists of a plurality of flat faces16, each of which corresponds in length and width to the length andwidth of shoulders 17, formed upon the opposite sides of the enlargedinner ends' 18 of the spokes. These ends 18 are of segmental form, sothat they fit against each other and between the flat inner faces of thetwo clamping plates or disks 13. The extreme inner ends of the enlargedportions 18 of the spokes bear against the sleeve 2, and the shoulders17 are engaged by the rims or flanges 15, so that the spokes are heldfirmly and secured in position. As will be readily seen upon referenceto Fig. 1, the two disks or plates .13 are clamped upon the spokesbetween the collars 4 9 of the sleeve and nut.

The outer end of the nut 8 of the sleeve is recessed, as at 11, in orderto receive a sleeve 19, provided upon a nut 20 which is screwed upon thethreaded outer end 8 of the spindle S. This sleeve 19 is of lessdiameter than the interior diameter of the recessed portion 11 of thenut 8 and is formed with an annular rib or bead 21, which is adapted toenter the recessed portion 11 and is of almost the same exteriordiameter as the interior diameter of said portion 11. This constructionprevents the entrance of dust and dirt between the sleeve and the nut 8,and hence between the spindle and the bearing-sleeve.

The construction and advantages of the invention will be readilyunderstood from the foregoing description, taken in connection with theaccompanying drawings. It will be seen that when a vehicle-hub isconstructed in this manner it may be quickly and easily repaired and oneor more spokes may be removed and replaced without removing thewheel-rim. By providing the clamping disks or plates 13 with the flanges15 and their flat faces 16 to engage the shoulders 17 upon the spokesthe latter are held rigidly in position and are prevented from turningand twisting.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, isa In a wheelhub, the combination of abearing-sleeve having an annular collar adjacent to one end andscrew-threads adjacent to its opposite end, spokes having tapered innerends formed on their opposite sides with shoulders, a nut havinginternal screwthreads on said sleeve and an annular collar, and a pairof clampin -disks upon said sleeve between its collar an the collar ofsaid nut, said disks having inwardly-projecting annular flanges formedon their inner sides with flat faces to engage the shoulders on saidspokes, substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing Witnesses.

MARTIN LUTHER PORTER.
